Chapter 8.9, Problem 22ATS

 (a)

Interpretation Introduction

Interpretation:

Major product should be found for the given alkene while adding bromine and water.

Concept introduction:

• Addition of bromine molecule in presence of water gives the halohydrin formation.
• Addition of bromine and hydroxide group across the double bond of alkene is known as halohydrin formation.
• Generally, bromination reactions proceeds through a 3-membered cyclic bromonium intermediate then attack of water molecule at most substituted carbon position of the alkene. 

To find: the major product formed during bromination (in ethanol) for the given alkene.
